Total Dissolved Solids

Water is classified as an excellent solvent. Because of this, it is able to snag impurities easily. In fact, the purest water, which is tasteless odorless, and colorless, is the best solvent there is. It’s true that having a few dissolved solids – minerals and sodium in very small doses – are actually beneficial to your health.

What Ions Mean to Your Water

The term TDS (Total Dissolved Solids) is the cumulative combination of any cations (positively charged) and anions (negatively charged) in your water. Having a test for TDS can tell you the total amount, but will not identify the nature of these ionic relationships.

A general rule of thumb is that, cations combined with carbonates, such as calcium (CaCO3) or magnesium (MgCO3) are associated with hardness, scale formation and bitter taste. Cations combined with chloride, such as sodium (NaCl) or potassium (KCl) can result in salty or brackish taste, and increase corrosivity

TDS and Overall Water Quality

The EPA classifies TDS as a secondary drinking water standard, which means it is more of an aesthetic issue than a health risk, such as lead. But the concentration of any of these dissolved ions can damage your home, hair and skin, and in rare cases, can be a detriment to your health.

The EPA Standard for TDS is limited to 500 milligrams per liter.

Methods for Treatment

There are different methods of filteration to treat TDS depending on the chemical makeup of your water. The best way to find this out is to schedule a water test with your local Culligan Man.

A typical solution to this problem is a reverse osmosis filter if you are concerned with your drinking water. However, a whole solution is also available if you feel the need to take care of the entirety of your water system.

Typical Contaminants and Sources for TDS

TDS can come from a number of sources, and the location of your home, climate, water treatment method, source, and a number of variables can contribute to the composition of your water. Common TDS contaminants can include ionic compounds derived from calcium, magnesium, potassium, sodium, chlorides, sulfates, phosphates and nitrates.

Industrial Wastewater and Sewage – treatment of both can include nitrates, which is important for animal growth. Algal blooms can be more likely to occur with the availability of nitrogen, causing an uptick in disinfectants being used by your municipality, which can lead to chlorine taste and smell. Phosphates can also be a non-point (water pollution from diffuse) source of TDS from wastewater treatment.

Urban Runoff – one of the leading sources in water quality problems, urban runoff occurs when rainwater runs across impervious surfaces through drainage systems. Some of these surfaces contain gasoline, motor oil, metals and trash, while lawns contain fertilizers and pesticides. Fertilizer is also a source of phosphorous and nitrates. Storm water runoff where de-icing salts are applied can also permeate drainage systems.

Piping/Hardware/Plumbing – the infrastructure of your own home could be the source of dissolved solids – particularly if the TDS is low. How can this be? Water in its purest form is a corrosive solvent, and can rake toxic materials such as lead and copper into your household problem This can be a major health risk. It’s a rare event the water source in your home is so low in TDS that it could become an issue, but if you are concerned about this, have your water tested today.

Sea Water – sea water, naturally, contains an excessive amount of NaCl (sodium) and other ionic compounds that can contribute to a salty or brackish taste. While there are a handful of desalination plants (designed to remove sodium compounds from sea water) in certain areas around the world, the hard truth is that purifying sea water takes an increased amount of time and energy to break such chemical bonds.

Agricultural/Farming/Irrigation Systems – just like in lawn treatment, synthetic farm fertilizers have nitrates that can dissolve into the soil. Elevated levels of nitrates also occur in animal waste and compost. Nitrogen is an essential nutrient for plant growth. But excess nitrogen can combine with organic materials on the surface to product nitrates, which can be harmful to drinking water systems.

Naturally Occurring – When water makes its way through the ground, it encounters layers of limestone and chalk. These beds are typically comprised partly of calcium and magnesium bicarbonates. The bi-product of these dissolved solids is hard water. More than 85% of U.S. households have hard water, according to studies.

Other Home Water Problems

Hard Water

Hard Water

Hard water is the result of mineral buildup in your city or well water, most commonly from calcium and lime. The signs of hard water are not always obvious, but can have detrimental effects on your home. Soap scum and stains are two of the most visible problems associate with hard water. Let your Culligan Man recommend which water softener is right for your home!

Bitter Taste

Bitter Taste

Bitter tasting water is often caused when the pH of your water is out-of-sync. Culligan has the equipment to fix the bitterness in your water. Let your Culligan Man recommend which water solution is right for your home!

Dry Skin/Hair

Dry Skin/Hair

Hard water will clog your pores, leaving your skin dry and itchy. Your hair can also become damaged and unmanageable due to hard water. Let your Culligan Man recommend which water softener is right for your home!

Salty Taste

Salty Taste

Water that tastes salty could be caused by sulfate concentration levels and geographic tendencies. Luckily, Culligan can remove the salty taste from your water. Let your Culligan Man recommend which water solution is right for your home!

Chromium-6

Chromium-6

Chromium-6 (or hexavalent chromium) has recently been discovered in limited amounts in some water supplies. Chromium six is suspected of being a carcinogen, and should not be ingested at amounts above the federally mandated limits. We have never been alarmists, but if you are concerned about the quality of the water you drink, you might want to consider a reverse osmosis system. Reverse Osmosis is the only readily available system that reduces chromium-6.

Arsenic

Arsenic

Arsenic can occur natural or is a byproduct of agricultural industry. In some cases, high arsenic levels can have negative effects on your health. Let your Culligan Man recommend a water solution to correct your arsenic problem.
